A trifluoromethanesulfonate (OTf) and tert -butylacetylene ( t BuC[triple bond, length as m-dash]C - ) co-protected silver nanocluster (NC), Ag 43 ( t BuC[triple bond, length as m-dash]C) 24 (CF 3 SO 3 ) 8 (Ag 43 ), was synthesized and characterized. Single crystal X-ray diffraction analysis revealed its total structure. 43 Ag atoms are arranged into a three-concentric-shell Ag@Ag 12 @Ag 30 structure. Both OTf and t BuC[triple bond, length as m-dash]C - ligands bonded with Ag atoms in a μ 3 mode. The application of Ag 43 as a catalyst for the reaction of silane with alcohol or H 2 O indicated that the surface ligands had a profound passivation effect, which significantly influenced the reactivity and selectivity.
